A New Look at Euclid's Second Proposition
There has been considerable interest during the past 2300 years in comparing different models of geometric computation in terms of their computing power. One of the most well-known results is Mohr's proof in 1672 that all constructions that can be executed with straightedge and compass can be carried out with compass alone. The earliest such proof of the equivalence of models of computation is ...
متن کاملA second look at bivalirudin.
a patient's hemostatic capacity by promoting the formation of thrombin. What happened to derail the development of bivalirudin after the initial promising findings? An angioplasty study comparing bivalirudin with UFH was conducted between 1993 and 1994 and reported in 1995. 8 Bivalirudin was found to be at least as effective as high-dose UFH in preventing ischemic complications in patients unde...
متن کاملA second look at the second law
It is commonly argued that the spectacular increase in order which has occurred on Earth does not violate the second law of thermodynamics because the Earth is an open system, and anything can happen in an open system as long as the entropy increases outside the system compensate the entropy decreases inside the system. However, if we define ‘‘X-entropy’’ to be the entropy associated with any d...
متن کاملA Second Look at General Markov ChainsDavid
In the spirit of Chapter 2, this is an unsystematic treatment of scattered topics which are related to topics discussed for reversible chains, but where reversibility plays no essential role. Section 1 treats constructions of stopping times with various optimality properties. Section 2 discusses random spanning trees associated with Markov chains, the probabilistic elaboration of \the matrix-tr...
متن کاملTransfinite progressions: a second look at completeness
1. Iterated Gödelian extensions of theories. The idea of iterating ad infinitum the operation of extending a theory T by adding as a new axiom a Gödel sentence for T , or equivalently a formalization of “T is consistent”, thus obtaining an infinite sequence of theories, arose naturally when Gödel’s incompleteness theorem first appeared, and occurs today to many non-specialists when they ponder ...
